Description

The The invention relates to a storage of a flap on a structure of a Motor vehicle specified in the preamble of claim 1 Art as well as a bodywork for Such a motor vehicle with the features of claim 5.

Such bearings of flaps on a structure of a motor vehicle, especially a coach, are well known and in the 1A to 3 shown. The 1A shows a lift flap 10 , which via a four-joint adjusting device 12 manually between a closing position closing an opening, which in the 1A is shown, and at least one opening releasing the open positions, which in the 1B is shown, is adjustable. This is the lift flap 10 with a support arm 14 hingedly connected, in turn, via a console 16 pivotally mounted about a pivot axis on the structure of the coach, not shown. In addition, the lift flap 10 with a guide arm 18 hingedly connected, which is also pivotally connected to said structure pivotally about a pivot axis. The guide arm 18 serves to stabilize the lift flap 10 so that it does not run unchecked around the hinged connection with the support arm 14 swings.

To assist the adjustment of the lift flap 10 from the closed position to the open position, wherein the lift flap 10 according to a directional arrow 20 is adjusted upward in the vehicle vertical direction is a gas spring 22 provided, on the one hand to the guide arm 18 and on the other hand on a frame element 24 the structure of the coach is pivotally supported about respective pivot axes.

From the Serienkraftwagenbau continue to be known and in the 2 it is shown that the adjusting device 12 a linear motor 26 may comprise, by means of which the lifting flap 10 can be brought from its closed position to its open position, without causing a person to open the lifting flap 10 have to apply their own strength. This is still a connecting pipe 28 provided, which the support arms 14 connects to each other, what the 3 can be clearly seen.

The known from the standard production car lift 10 has the disadvantage that the integration of the lift valve 10 with the linear motor 26 a great effort must be made, which is a change in the structure and the flap 10 even with respect to the manually operated flap 10 according to the 1A and 1B means. On the one hand, this leads to an undesirable cost increase and to a reduction of the available storage space, the through the flap 10 can be covered or released. Furthermore, there is a negative influence of tolerances of the frame elements 24 comprehensive framework, exemplified by a framework 30 according to 3 is shown.

It is therefore an object of the present invention, a storage of a Flap on a body of a motor vehicle and a bodywork for a motor vehicle to provide, which allow easy operation of the flap and low cost.

These Task is by a storage of a flap on a structure of a Motor vehicle with the features of claim 1 and by a Bodywork for a motor vehicle with the features of claim 5 solved. Advantageous embodiments with functional and non-trivial developments of the invention are indicated in the dependent claims.

A Inventive storage a flap, door or similar wing element on a construction of a motor vehicle, in particular a coach, in which at least one adjusting device with at least one Actuator is provided by means of which the flap or the like between one an opening closing closed position at least one of the opening at least partially releasing open position is adjustable, is characterized by the fact that the actuator of the actuator firmly held on the flap or the like and at an adjustment between the closed position and the open position is mitbewegbar.

Of the Actuator of the adjusting device allows a particularly simple Adjustment of the flap from its closed position in the at least an open position and vice versa without a person, such as a driver of the motor car, has to muster his own strength. Much more Can the adjustment of the flap automatically and thus especially comfortable, for example by pressing a button or flipping a lever or the like, take place.

In addition, the storage according to the invention has low costs, as by the relative to the flap fixed support of the actuator and its co-movement in the adjustment a simple integration of this automatically actuated flap in the car without changes to the structure and / or any frame for holding the flap is possible. Already existing, inexpensive and manually operated flaps are characterized by the storage according to the invention in a simple and cost-effective manner by the automatic, ie by means of Foreign power, operable flap of the storage according to the invention interchangeable, without having to make changes to the existing motor vehicle, its structure, any frame or the like. This is accompanied by the maintenance of a very large volume, for example a storage space, which can be opened or closed by the flap of the storage according to the invention. Furthermore, the storage according to the invention is independent of tolerances of the structure, for example, the shell, the motor vehicle, since the actuator integrated into the flap and thus an additional, tolerance-sensitive interface between actuator and structure is avoided.

at a particularly advantageous embodiment of the invention the actuator is designed as a rotary drive. In this case generated So the actuator is a torque and a rotary motion, wherein the torque on the flap side on the structure or possibly on a support frame of the motor vehicle, which is to hold the flap transferred becomes. Thus, the support takes place the torque on the flap instead of the body or shell of the motor vehicle.

One Another advantage of the rotary drive is that a force or torque effect of the rotary drive not over Lever and certain kinematics in a rotary motion for illustration a pivoting about a pivot axis of the flap converted Must be, thereby adjusting the flap between its open position and their closed position particularly energy efficient and thus without particularly large and unwanted losses feasible.

advantageously, is the actuator over a Strut assembly held on the flap, which has the advantage that thereby a particularly large-scale support of Force action of the actuator is realized on the flap. This avoids a selective introduction of force and thus a related on a surface particularly high force transmission, resulting in a long service life and a very good functional safety over ensures this long life of storage according to the invention. The holder and thus the support The actuator on the flap can also have defined connection points done by the strut assembly by a certain distance spaced apart to represent a particularly advantageous and even force application in the flap.

The The invention also relates to a bodywork for a motor vehicle, in particular a coach, with at least one storage according to the invention, wherein in one embodiment by means of the actuator at least one rotatably connected to the actuator Rotating rod of the adjusting device is rotatable, which with at least one at least substantially obliquely, in particular vertically, to the torsion bar extending pivot arm of the actuator rotatably is connected, wherein the pivot arm pivotable about a pivot axis is held on the structure. This is the flap over the Actuator, the torsion bar and the swivel arm held on the structure, particularly easy to adjust and inexpensive to integrate in the car. Advantageously, the torsion bar is rotatably supported on the flap, which with an improved introduction of force and support of the actuator in or at the flap goes along.

Further Advantages, features and details of the invention will become apparent the following description of a preferred embodiment as well as from the drawings. The above in the description mentioned features and feature combinations and the following mentioned in the description of the figures and / or in the figures alone shown features and feature combinations are not only in the each specified combination, but also in other combinations or used alone, without the scope of the invention to leave.

The Drawings show in:

1A a side view of a lift flap for a coach according to the prior art in a closed position;

1B a side view of the lifting flap according to 1A in an open position;

2 a perspective view of a linear motor for actuating a further embodiment of a lift flap for a coach according to the prior art;

3 a perspective view of the means of the linear motor according to 2 actuatable lifting flap in an open position;

4 a perspective view of an embodiment of the storage according to the invention.

While the 1 to 3 Lifting flaps for coaches according to the prior art show that shows 4 a storage of such a lifting flap, which allows easy operation and a very cost-effective integration of this in a coach.

The 4 shows a storage 32 a lift flap 10 ' on a construction 34 a coach, the construction 34 in the vehicle vertical direction according to a directional arrow 35 running frame ELEMENTS 36 and 38 and in the vehicle longitudinal direction according to a directional arrow 48 running frame elements 42 and 44 includes. The frame elements 36 . 38 . 42 and 44 limit an opening 46 , via which a storage space of the coach for the accommodation of luggage or the like is accessible.

During storage 32 is an adjusting device 12 ' provided, the pivot arms 48 , Guide arms 18 ' as well as torsion bars 50 and gas springs 22 ' includes. Furthermore, the adjusting device comprises 12 ' an actuator in the form of a pneumatically actuated rotary drive 52 , by means of which the lifting flap 10 ' between one the opening 46 occlusive and in the 4 shown closed position and at least one of the opening 46 releasable open position is adjustable.

Again 4 it can be seen, is the rotary drive 52 relative to the lift flap 10 ' firmly held on this and mitbewegbar in an adjustment of this between the closed position and the open position. The rotary drive 52 generates a rotational movement and a torque, which flap side on the adjusting device 12 ' is transmitted. By a through the adjusting device 12 ' shown compulsive kinematics causes a rotation of the torsion bars 50 by the rotary motion of the actuator 52 an opening or closing the lift flap 10 , These are the swivel arms 48 on the one hand via respective consoles 54 on the construction 34 about a respective parallel to the vehicle longitudinal direction according to the directional arrow 40 pivot axis extending pivotally held. On the other hand, the pivot arms 48 rotatably with one of the torsion bars 50 connected, being perpendicular to the torsion bars 50 run. The torsion bars 50 in turn are rotatable about respective consoles 56 at the lift flap 10 ' supported, whereby a defined and safe opening of the flap is realized.

To supplement the adjusting device 12 ' to a four-joint actuator 12 ' are the guide arms 18 ' provided, on the one hand pivotable about a pivot axis of the frame elements 38 and on the other hand pivotable about a pivot axis on the lift flap 10 ' held and supported.

gas springs 22 ' serve the purpose of adjusting the lift flap 10 ' between their open position and their closed position to support, so that the use of a smaller-sized and possibly less powerful rotary drive 52 to allow for what the cost of storage 32 keeps in a small frame.

Again 4 can be seen further, is the rotary drive 52 via a strut arrangement 58 at the lift flap 10 ' held and supported on this, resulting in an area force or torque introduction of the rotary drive 52 on the lift flap 10 ' results. The strut arrangement 58 includes for this purpose Blechkantteile 60 and 62 , To create a certain stability of the lift flap 10 ' , which is designed as a sheet metal flap, it has a rib structure 60 on, with ribs of the rib structure 60 have a trapezoidal cross-section. Representative of this is such a rib 62 mentioned in the field of rotary drive 52 has a cutout to the rotary drive 52 at least almost space-neutral in the lift flap 10 ' integrate.

During storage 32 Thus, it is a solution that can be easily and inexpensively integrated into the coach, without changes to its shell, which, for example, the structure 34 with the frame elements 36 . 38 . 42 and 44 includes having to perform while implementing an automatic operation of the flap, without that a person such as a driver of the coach own strength to adjust the lift flap 10 ' would have to raise.
